GPS Port PinoutThe platform is capable of receiving or sourcing GPS signals of 1 PPS & 10 MHz. These interfaces areprovided by two mini-coax 50-Ohm, 1.0/2.3 DIN series connector on the front panel. Similarly there are twomini-coax 50-Ohm connectors provided in the front panel to output this 1PPS and 10MHz.
The table below summarizes the GPS port pinouts.

The table below summarizes the TOD pinout for A900-RSP2A and A900-RSP3-3C-400 modules.
This port requires the use of SHIELDED cable for GR-1089-core “Intra-Bldg lightning surge” protection.RS422 interface is per industry standard EIA-422 /RS422 specification.
Note
In order to comply with IEEE 1613.1-2013 the cables used to connect the 10MHz and 1PPS ports to otherequipment must be less than 2 meters long in order to protect these ports from exposure to damaging transients.
Note
In order to comply with IEC 61850-3:2013 the 10MHz and 1PPS ports must be classified as Class 1 ReliabilityLevel for Local Connection use in order to protect these ports from exposure to damaging transients.

USB Console Port PinoutTwo individual Type-A USB connector are used for USB console and USB mass storage. One single USB2.0 Type-A receptacle is provided on the RSP front panel for providing console access to ROMMON, IOS-XEand diagnostics. It operates as a USB peripheral only for connection to an external host PC. This requires theuse of a Type-A to Type-A connector instead of a standard USB cable.
The use of the USB console is mutually exclusive with the RS232 console/Aux port. While a USB cable isinserted, access is automatically switched to this port.
Note
The other single USB 2.0 Type-A receptacle is provided on the RSP front panel for inserting external USBmass storage devices such as standard USB flash drives. It is used to load images, store configurations, writelogs, etc. It supports operation up to 12Mbps.

Fiber-Optic SpecificationsThe specification for optical fiber transmission defines two types of fiber: single-mode and multimode.Withinthe single-mode category, three transmission types are defined: short reach, intermediate reach, and longreach.Within the multimode category, only short reach is available. For information about optical SFPmodules,see the documentation for the SFP module at:
http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html .
Cabling GuidelinesThe guidelines are recommended during the installation of fiber cables:
• Avoid the following actions that can stress the cable:
• Pulling or stretching beyond the specified pulling load rate• Bending it beyond the specified bend radius
Troubleshooting16
TroubleshootingUSB Flash/MEM Port Pinout
• Creating tension in the suspension runs
• Do not touch the fiber tips of fiber cables.• Use single mode or multi-mode optical fiber cables as per the optical transceiver requirement.• Use fiber cleaner to clean the fiber tip as well as transceiver before inserting the fiber cable into theoptical transceiver during installation.
• To avoid excessive bending of fiber cable and efficient routing of cables, cable guides or cable bracketsare recommended to be used with the chassis.
LED SummaryThe following sections describe the meanings of the LEDs on the Cisco ASR 903 Router.
RSP LEDsThe table below summarizes the RSP LEDs for the supported RSP modules.
Amajor alarm condition indicates the failure of a single fan in the fan tray; a critical alarm indicates the failureof multiple fans. In the event that a single fan fails, the Cisco ASR 903 Router software adjusts the fan speedto prevent excessive heat within the chassis.
